I think his question is why you didn't just connect the Gerbing's leads directly to the battery. It seems to me that would have been massively easier, as long as you don't mind having it unswitched.

Slick install though.

Exactly that, I wanted it switched. Also, I don't like a bunch of stuff coming off the battery. This way only one thing is connected to the battery and I can plug and play whatever I need off of the PDM60. I Like the PDM60 because there are no fuses to blow, the downside is if it takes a crap you are out of luck I guess.
